1 FIG. 100 101 102 102 101 As shown in, a communication method provided by an embodiment of the present disclosure may be applied to a wireless communication system. The wireless communication system may include a network deviceand user equipment, where the user equipmentis configured to support carrier aggregation and may be connected to a plurality of carrier units of the network device, including a main carrier unit and one or more auxiliary carrier units.

100 100 It is to be understood that the above wireless communication systemmay be applicable to a low-frequency scenario, or may also be applicable to a high-frequency scenario. Application scenarios of the wireless communication systeminclude, but are not limited to, a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a worldwide interoperability for micro wave access (WiMAX) communication system, a cloud radio access network (CRAN) system, a future 5th-Generation (5G) system, a new radio (NR) communication system or a future evolved public land mobile network (PLMN) system, etc.

102 102 101 The user equipmentshown above may be a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent, or a terminal device, etc. The user equipmentmay have a wireless transmission and reception function, and may communicate (e.g., wirelessly communicate) with one or more network devices of one or more communication systems and receive network services provided by the network device. The network device here includes, but is not limited to, the network deviceshown in the drawings.

102 The user equipmentmay be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device or a computing device having a wireless communication function, or other processing devices connected to a wireless modem, an in-vehicle device, a wearable device, a terminal in a future 5G network, or a terminal in a future evolved PLMN network, etc.

101 101 101 101 101 The network devicemay be an access network device (or referred to as an access network website). The access network device refers to a device that provides a network access function, such as a radio access network (RAN) base station, etc. The network devicemay specifically include a base station (BS), or includes the base station and a radio resource management device for controlling the base station, etc. The network devicemay further include a relay station (relay device), an access point, and a base station in the future 5G network, a base station in the future evolved PLMN network, or an NR base station, etc. The network devicemay be a wearable device or an in-vehicle device. The network devicemay also be a communication chip having a communication module.

101 For example, the network deviceincludes, but is not limited to, a next generation node B (gnodeB, gNB) in 5G, an evolved node B (eNB) in the LTE system, a radio network controller (RNC), a node B (NB) in a WCDMA system, a radio controller in the CRAN system, a base station controller (BSC), a base transceiver station (BTS) in a GSM system or a CDMA system, a home base station (e.g., a home evolved nodeB or a home node B (HNB)), a baseband unit (BBU), a transmitting and receiving point (TRP), a transmitting point (TP), or a mobile switching center, etc.

102 101 101 102 In a network energy saving project, in order to ensure that the user equipmentmay perform reasonable processing while the network deviceis in a DTX or DRX, the network deviceneeds to inform the user equipmentin advance of a time-domain parameter of a DTX or DRX state.

101 The signaling overhead is lower in a case where the time-domain parameter of the DTX or DRX state is semi-statically configured via higher-layer signaling. However, when a service feature changes, the network deviceneeds to re-configure a time-domain parameter that matches the new service feature, or to un-configure the original time-domain parameter, which results in poor flexibility. Re-configuration of the time-domain parameter via the higher-layer signaling further needs a longer latency.

2 FIG. 2 FIG. 2 FIG. 201 204 An embodiment of the present disclosure provides a communication method. Referring to,is a flowchart of an interaction of a communication method according to an example. As shown in, the method includes steps Sto S.

201 101 102 Specifically, in step S, a network devicetransmits configuration information to user equipment. The configuration information is configured to determine configuration parameters of at least one discontinuous transmission and reception pattern corresponding to each of at least one serving carrier.

102 The serving carrier corresponds to a serving cell of the user equipment.

101 101 In some possible implementations, the network deviceconfigures discontinuous transmission and reception patterns in a unit of carrier, for example, the network devicemay configure one or more discontinuous transmission and reception patterns for each carrier. At least one configuration parameter is different between different discontinuous transmission and reception patterns.

101 In some possible implementations, when the network deviceconfigures a plurality of discontinuous transmission and reception patterns for one carrier, each discontinuous transmission and reception pattern may be adapted to a corresponding service feature or service type, and thus the plurality of discontinuous transmission and reception patterns may match different service features or service types respectively.

In some possible implementations, the discontinuous transmission and reception pattern may include at least one of: a DRX pattern (a cell DRX on-off pattern), a DTX pattern (a cell DTX on-off pattern), or a DRX and DTX pattern pair (the cell DRX on-off pattern and the cell DTX on-off pattern).

For the DRX and DTX pattern pair, there is a correspondence between the DRX pattern and the DTX pattern. For example, the DRX and DTX pattern pair includes DRX patterns and corresponding DTX patterns which are bound one to one.

102 It is worth noting that there is a certain correlation between a DRX pattern and a DTX pattern of a cell. For example, in the DTX pattern, the cell may not transmit uplink/downlink scheduling information, or may also not transmit a reference signal. Correspondingly, during the corresponding duration in the DTX pattern, the user equipmentdoes not have uplink data scheduled and does not need to transmit a channel state information report (CSI report). Thus, the cell does not need to perform uplink reception. A state where the cell does not need to perform uplink reception may be considered as being in the DRX pattern. Therefore, the DRX and DTX pattern pair may be configured as needed in the embodiment of the present disclosure.

101 101 In some possible implementations, one cycle of the discontinuous transmission and reception pattern may include a first duration and a second duration. The first duration may be an energy saving duration, i.e., a duration during which the network deviceskips data transmission and reception (an off duration). The second duration is a duration during which the network devicenormally performs the data transmission and reception in the discontinuous transmission and reception pattern (an on duration).

101 101 102 101 In an example, the DRX pattern includes a first duration (a DRX-off duration) and a second duration (a DRX-on duration). For a cell configured with a cell DRX pattern, the network devicemay skip reception of at least part of uplink information during the first duration, for example, the network devicedoes not receive some signals periodically transmitted by the user equipment. The network devicereceives the uplink information normally during the second duration.

3 FIG. 101 101 101 In an example, as shown in, the DTX pattern includes a first duration (a DTX-off duration) and a second duration (a DTX-on duration). For a cell configured with a cell DTX pattern, the network devicemay skip transmission of at least part of downlink information during the first duration, for example, the network devicedoes not transmit some periodic signals. The network devicetransmits the downlink information normally during the second duration.

101 101 102 Referring to the above examples of the states of the network devicein the discontinuous transmission and reception pattern, it can be known that the network device, when in the discontinuous transmission and reception pattern, affects signal transmission and reception of the user equipment.

202 102 In step S, the user equipmentreceives the configuration information.

203 101 102 In step S, the network devicetransmits first indication information to the user equipment. The first indication information is configured to activate a first discontinuous transmission and reception pattern among the at least one discontinuous transmission and reception pattern.

In some possible implementations, the first discontinuous transmission and reception pattern is a currently activated discontinuous transmission and reception pattern, and may be a discontinuous transmission and reception pattern that matches a current service feature.

101 In some possible implementations, the network devicemay transmit the first indication information via Downlink Control Information (DCI) or a Media Access Control Control Element (MAC CE).

101 In some possible implementations, when the network deviceconfigures a discontinuous transmission and reception pattern, the first indication information may indicate whether to activate the discontinuous transmission and reception pattern via a set information field.

101 In some possible implementations, when the network deviceconfigures a plurality of discontinuous transmission and reception patterns, the first indication information may include an information field corresponding to each discontinuous transmission and reception pattern, and indicate whether to activate a corresponding discontinuous transmission and reception pattern via each information field.

101 In some possible implementations, in a case where a service feature changes, the network devicemay activate a discontinuous transmission and reception pattern that matches the new service feature, and does not need to re-configure the discontinuous transmission and reception pattern via higher-layer signaling, so as to save the configuration latency.

204 102 In step S, the user equipmentreceives the first indication information.

102 101 101 102 102 In some possible implementations, the user equipmentmay obtain an energy saving state of the network deviceafter receiving the first indication information, which facilitates adaptive operations. For example, when the network deviceis in the first duration of the DTX pattern, the user equipmentmay adaptively skip downlink reception to achieve energy saving of the user equipment.

101 102 102 102 101 102 101 In the embodiment of the present disclosure, the network deviceconfigures one or more discontinuous transmission and reception patterns for the user equipmentby transmitting the configuration information to the user equipment, and indicates the currently activated first discontinuous transmission and reception pattern by transmitting the first indication information to the user equipment. Thus, the network deviceactivates the required discontinuous transmission and reception pattern by flexible signaling indication, which may not only save the configuration time, but also be beneficial for the user equipmentto adapt to the discontinuous transmission and reception pattern of the network deviceto perform related operations.

101 401 402 4 FIG. 4 FIG. 4 FIG. An embodiment of the present disclosure provides a communication method. The method is performed by a network device. Referring to,is a flowchart of a communication method according to an example. As shown in, the method includes steps Sand S.

401 101 102 Specifically, in step S, a network devicetransmits configuration information to user equipment. The configuration information is configured to determine configuration parameters of at least one discontinuous transmission and reception pattern corresponding to each of at least one serving carrier.

102 The serving carrier corresponds to a serving cell of the user equipment.

101 101 101 In some possible implementations, the network deviceconfigures discontinuous transmission and reception patterns in a unit of carrier, for example, the network devicemay configure one or more discontinuous transmission and reception patterns for one carrier, and at least one configuration parameter is different between different discontinuous transmission and reception patterns. Alternatively, the network deviceconfigures one or more discontinuous transmission and reception patterns for each of a plurality of carriers.

101 In some possible implementations, when the network deviceconfigures a plurality of discontinuous transmission and reception patterns for one carrier, each discontinuous transmission and reception pattern may be adapted to a corresponding service feature or service type, and thus the plurality of discontinuous transmission and reception patterns may match different service features or service types respectively.

a DRX pattern; a DTX pattern; or a DRX and DTX pattern pair, where the DRX and DTX pattern pair includes a DRX pattern and a DTX pattern corresponding to the DRX pattern. In some possible implementations, the discontinuous transmission and reception pattern includes one of:

101 In an example, the network deviceconfigures a plurality of DRX patterns, a plurality of DTX patterns, or a plurality of DRX and DTX pattern pairs for one carrier.

In an example, each discontinuous transmission and reception pattern may be configured with corresponding configuration parameters.

a time-domain period; a start offset; a length of a first duration; or a length of a second duration. In some possible implementations, the configuration parameters include at least one of:

The first duration is a duration during which the network device skips data transmission and reception in the discontinuous transmission and reception pattern, and the second duration is a duration during which the network device performs the data transmission and reception in the discontinuous transmission and reception pattern.

In an example, one DRX time-domain period of the DRX pattern includes a first duration (a DRX-off duration) and a second duration (a DRX-on duration). The configuration parameters may include a value, a start offset, a length of the DRX-off duration, and a length of the DRX-on duration of the one DRX time-domain period.

In an example, one DTX time-domain period of the DTX pattern includes a first duration (a DTX-off duration) and a second duration (a DTX-on duration). The configuration parameters may include a value, a start offset, a length of the DTX-off duration, and a length of the DTX-on duration of the one DTX time-domain period.

In an example, configuration parameters of a DRX and DTX pattern pair include time-domain parameters of a DRX pattern and time-domain parameters of a DTX pattern corresponding to the DRX pattern. For example, the configuration parameters include a value, a start offset, a length of a DRX-off duration and a length of a DRX-on duration of a time-domain period of the DRX pattern, and a value, a start offset, a length of a DTX-off duration and a length of a DTX-on duration of a time-domain period of a DTX pattern corresponding to the DRX pattern.

In some possible implementations, different discontinuous transmission and reception patterns may have different configuration parameters.

101 For example, taking the DTX pattern as an example, the network deviceconfigures two DTX patterns: Pattern 1 and Pattern 2. Pattern 1 has a longer time-domain period and is suitable for a scenario with sparse services. Pattern 2 has a shorter time-domain period and is suitable for a scenario with more frequent service arrival. In an example, the time-domain period of Pattern 1 may be an integer multiple of the time-domain cycle of Pattern 2.

402 101 102 In step S, the network devicetransmits first indication information to the user equipment. The first indication information is configured to activate a first discontinuous transmission and reception pattern among the at least one discontinuous transmission and reception pattern.

In some possible implementations, the first discontinuous transmission and reception pattern is a currently activated discontinuous transmission and reception pattern, and may be a discontinuous transmission and reception pattern that matches a current service feature.

101 In some possible implementations, the network devicemay transmit the first indication information via DCI or an MAC CE.

101 In some possible implementations, in a case where a service feature changes, the network devicemay activate a discontinuous transmission and reception pattern that matches the new service feature, and does not need to re-configure the discontinuous transmission and reception pattern via higher-layer signaling, so as to save the configuration latency.

101 102 102 102 101 In the embodiment of the present disclosure, the network deviceconfigures one or more discontinuous transmission and reception patterns for the user equipmentby transmitting the configuration information to the user equipment, and indicates the currently activated first discontinuous transmission and reception pattern by transmitting the first indication information to the user equipment. Thus, the network deviceactivates the required discontinuous transmission and reception pattern by flexible signaling indication, so as to save the configuration time.

101 401 402 An embodiment of the present disclosure provides a communication method. The method is performed by a network device. The method includes steps Sand S.

401 101 102 Specifically, in step S, a network devicetransmits configuration information to user equipment. The configuration information is configured to determine configuration parameters of at least one discontinuous transmission and reception pattern corresponding to each of at least one serving carrier.

402 101 102 In step S, the network devicetransmits first indication information to the user equipment. The first indication information is configured to activate a first discontinuous transmission and reception pattern among the at least one discontinuous transmission and reception pattern.

at least one first information field; at least one second information field; or at least one third information field. The first indication information includes at least one of:

The first information field is configured to indicate activation or inactivation of a corresponding DRX pattern, the second information field is configured to indicate activation or inactivation of a corresponding DTX pattern, and the third information field is configured to indicate activation or inactivation of a corresponding DRX and DTX pattern pair.

401 402 The implementations of steps Sand Smay be referred to the description of the aforementioned embodiment, which are not repeated here.

101 In some possible implementations, when the network devicetransmits the first indication information via DCI or an MAC CE, the DCI or MAC CE may include at least one of a first information field, a second information field, or a third information field.

In some possible implementations, each first information field may include N1 bits, where N1 is greater than or equal to 1. Activation or inactivation of a corresponding DRX pattern is indicated via values of the N1 bits in the first information field. For example, the first information field being a set value represents inactivation of the DRX pattern.

In some possible implementations, each second information field may include N2 bits, where N2 is greater than or equal to 1. Activation or inactivation of a corresponding DTX pattern is indicated via values of the N2 bits in the second information field. For example, the second information field being a set value represents inactivation of the DTX pattern.

It is to be understood that the DRX pattern may be independently activated or inactivated according to the first information field, and the DTX pattern may be independently activated or inactivated according to the value of the second information field.

In some possible implementations, each third information field may include N3 bits, where N3 is greater than or equal to 1. Activation or inactivation of a corresponding DRX and DTX pattern pair is indicated via values of the N3 bits in the third information field. For example, the third information field being a set value represents inactivation of a group of DRX pattern and DTX pattern that are bound in a corresponding DRX and DTX pattern pair.

In the implementation, a DRX pattern and its corresponding DTX pattern are bound together to be activated or inactivated according to the value of the third information field.

In some possible implementations, each of the at least one first information field is configured to indicate activation or inactivation of a DRX pattern of a corresponding carrier, or is configured to indicate activation or inactivation of a DRX pattern of a corresponding carrier group.

101 101 In an example, N1 is 1 when the network deviceconfigures one DRX pattern for one carrier, and N1 is greater than 1 when the network deviceconfigures a plurality of DRX patterns for one carrier.

101 In an example, when there are a plurality of first information fields, the number of first information fields is related to the number of carriers. For example, there are M1 first information fields if the network deviceconfigures at least one DRX pattern for each of M1 carriers. As shown in Table 1, each first information field corresponds to one carrier.

101 In an example, when there are a plurality of first information fields, the number of first information fields may also be related to the number of carrier groups. For example, the network deviceconfigures at least one DRX pattern for each carrier group. As shown in Table 1, each first information field corresponds to one carrier group.

Each carrier group includes at least one carrier. Each carrier group corresponds to at least one DRX pattern. When a certain DRX pattern corresponding to a carrier group is activated, it is considered that the same DRX pattern is activated for each carrier in the carrier group.

In some possible implementations, each of the at least one second information field is configured to indicate activation or inactivation of a DTX pattern of a corresponding carrier, or is configured to indicate activation or inactivation of a DTX pattern of a corresponding carrier group.

101 101 In an example, N2 is 1 when the network deviceconfigures one DTX pattern for one carrier, and N2 is greater than 1 when the network deviceconfigures a plurality of DTX patterns for one carrier.

101 101 In an example, when there are a plurality of second information fields, as shown in Table 2, the number of second information fields is related to the number of carriers or the number of carrier groups. For example, there are M2 second information fields if the network deviceconfigures at least one DTX pattern for each of M2 carriers. Alternatively, the network deviceconfigures at least one DTX pattern group for each of M2 carrier groups.

Each carrier group corresponds to at least one DTX pattern. For a carrier group, the DTX pattern activated for each carrier in the carrier group are the same.

TABLE 2 1st second information field Carrier 1 Carrier group 1 2nd second information field Carrier 2 Carrier group 2 . . . . . . . . . M2-th second information field Carrier M2 Carrier group M2

In some possible implementations, each of the at least one third information field is configured to indicate activation or inactivation of a DRX and DTX pattern pair of a corresponding carrier, or is configured to indicate activation or inactivation of a DRX and DTX pattern pair of a corresponding carrier group.

101 101 In an example, N3 is 1 when the network deviceconfigures one DRX and DTX pattern pair for one carrier, and N3 is greater than 1 when the network deviceconfigures a plurality of DRX and DTX pattern pairs for one carrier.

101 101 In an example, when there are a plurality of third information fields, as shown in Table 3, the number of third information fields is related to the number of carriers or the number of carrier groups. For example, there are M3 third information fields if the network deviceconfigures at least one DRX and DTX pattern pair for each of M3 carriers. Alternatively, the network deviceconfigures at least one DRX and DTX pattern pair group for each of M3 carrier groups.

Each carrier group corresponds to at least one DRX and DTX pattern pair. For a carrier group, the DRX and DTX pattern pair activated for each carrier in the carrier group are the same.

101 101 101 In the embodiment of the present disclosure, the network devicedynamically indicates, via different information fields in the first indication information, whether to activate a corresponding discontinuous transmission and reception pattern. Thus, in a scenario where the network deviceconfigures a plurality of discontinuous transmission and reception patterns in a unit of carrier, the network devicemay activate a required discontinuous transmission and reception pattern according to a current service feature, which has higher flexibility and may effectively save the configuration latency.

101 401 402 The embodiments of the present disclosure provide a communication method. The method is performed by a network device. The method includes steps Sand S.

401 402 The implementations of steps Sand Smay be referred to the description of the aforementioned embodiment, which are not repeated here.

101 In some possible implementations, when the network devicetransmits the first indication information via DCI or an MAC CE, the DCI or MAC CE may include at least one of a fourth information field, a fifth information field, or a sixth information field.

In some possible implementations, the first indication information may further include at least one of a first information field, a second information field, or a third information field. In such case, the implementation may be referred to the description of the above-mentioned embodiment.

102 101 102 In the embodiment of the present disclosure, the user equipmentobtains the situation of information fields in the first indication information according to the first signaling transmitted by the network device, and thus the user equipmentmay obtain information of a corresponding information field in a targeted manner, which is conducive to improving signaling processing efficiency.

102 601 602 601 600 602 An embodiment of the present disclosure provides a communication method. The method is performed by user equipment. The method includes steps Sand S, or the method includes steps S, S, and S.

101 The network devicemay transmit first indication information via DCI or an MAC CE.

unicast DCI; multicast DCI; or broadcast DCI. In a case where the first indication information is transmitted via the DCI, the DCI is one of:

In some possible implementations, CRC of the multicast DCI is scrambled using a first RNTI, CRC of the broadcast DCI is scrambled using a second RNTI, and the unicast DCI is scrambled using a UE-specific RNTI.

101 101 The first RNTI is a common RNTI for a group of UE, and is configured by the network device. The second RNTI is a common RNTI for all UE in a cell, and may be configured by the network devicevia broadcast signaling or defined by a protocol.

In a case where the first indication information is transmitted via the MAC CE, the MAC CE is UE-specific signaling.

101 102 In some possible implementations, the network devicemay configure the same manner for transmitting an MAC CE for different user equipment.

101 102 In the embodiment of the present disclosure, the network devicemay transmit the first indication information to the user equipmentin different transmission manners, so as to dynamically activate or inactivate a corresponding discontinuous transmission and reception pattern.

102 601 602 An embodiment of the present disclosure provides a communication method. The method is performed by user equipment. The method includes steps Sand S′.

601 102 101 Specifically, in step S, the user equipmentreceives configuration information transmitted by a network device. The configuration information is configured to determine configuration parameters of at least one discontinuous transmission and reception pattern corresponding to each of at least one serving carrier.

602 102 101 In step S′, the user equipmentreceives first indication information transmitted by the network deviceon a primary cell, or receives first indication information that is applicable to a secondary cell and transmitted by the network device.

101 In some possible implementations, the network devicemay transmit the first indication information via DCI or an MAC CE.

102 In some possible implementations, in a case where the first indication information is transmitted on the primary cell, the method may further include the following step. The user equipmentmonitors the first indication information on a carrier corresponding to the primary cell.

102 102 In this step, when the first indication information is transmitted on the primary cell (Pcell), the user equipmentmay monitor the first indication information merely on the primary cell, and does not need to monitor the first indication information on all serving cells or serving carriers, which may effectively reduce the monitoring energy consumption of the user equipment.

102 In some possible implementations, in a case where the first indication information is applicable to the secondary cell, the method may further include the following step. The user equipmentcommunicates with the secondary cell according to the first indication information.

102 102 In this step, when the first indication information is merely applied to the secondary cell (scell), the discontinuous transmission and reception pattern is merely applied to the secondary cell, that is, the secondary cell enters the discontinuous transmission and reception pattern, and skips data transmission and reception during a certain duration. The user equipmentneeds to perform an adaptive operation when the secondary cell skips the data transmission and reception. For example, in a case where the secondary cell is in a DRX pattern, the secondary cell skips uplink data reception during a first duration, and the user equipmentmay skip uplink data transmission during the first duration.

102 In this step, the primary cell may be in a service-available state at all times, which may thus avoid communication interruption between the user equipmentand the primary cell.

102 601 602 An embodiment of the present disclosure provides a communication method. The method is performed by user equipment. The method includes steps Sand S.

601 102 101 Specifically, in step S, the user equipmentreceives configuration information transmitted by a network device. The configuration information is configured to determine configuration parameters of at least one discontinuous transmission and reception pattern corresponding to each of at least one serving carrier.

602 102 101 In step S, the user equipmentreceives first indication information transmitted by the network device. The first indication information is configured to activate a first discontinuous transmission and reception pattern among the at least one discontinuous transmission and reception pattern.

102 The first discontinuous transmission and reception pattern is activated at a moment when the user equipmentreceives the first indication information.

In some possible implementations, the first discontinuous transmission and reception pattern may be a DRX pattern, a DTX pattern, or a DRX and DTX pattern pair.

In some possible implementations, the moment when the first indication information is received refers to a moment when the first indication information is monitored and processing of the first indication information, such as demodulation, is completed.

101 In some possible implementations, in a scenario where the first discontinuous transmission and reception pattern is activated, the network devicemay apply the first discontinuous transmission and reception pattern. For example, during the time-domain period of the first discontinuous transmission and reception pattern, data transmission and reception is skipped during a first duration, and the data transmission and reception is normally performed during a second duration.

101 102 101 102 In some possible implementations, when the network deviceis in the first discontinuous transmission and reception pattern, the user equipmentmay also perform adaptive energy saving operations. For example, when the network devicedoes not transmit downlink information during the first duration, the user equipmentmay not monitor the downlink information during the first duration to achieve energy saving.

102 601 603 An embodiment of the present disclosure provides a communication method. The method is performed by user equipment. The method includes steps Sto S.

601 102 101 Specifically, in step S, the user equipmentreceives configuration information transmitted by a network device. The configuration information is configured to determine configuration parameters of at least one discontinuous transmission and reception pattern corresponding to each of at least one serving carrier.

602 102 101 In step S, the user equipmentreceives first indication information transmitted by the network device. The first indication information is configured to activate a first discontinuous transmission and reception pattern among the at least one discontinuous transmission and reception pattern.

102 The first discontinuous transmission and reception pattern is activated at a moment when the user equipmentreceives the first indication information.

603 In step S, a second discontinuous transmission and reception pattern is activated after a second time-domain position when second indication information corresponding to the second discontinuous transmission and reception pattern is received at a first time-domain position. The first time-domain position is within a time-domain period of the first discontinuous transmission and reception pattern.

In some possible implementations, the first time-domain position may be within the time-domain period corresponding to the first discontinuous transmission and reception pattern, for example, within the first duration or the second duration of the first discontinuous transmission and reception pattern.

In some possible implementations, information formats or transmission manners of the second indication information and the first indication information may be the same. For example, the second indication information may include a first information field, a second information field, or a third information field.

In some possible implementations, the second discontinuous transmission and reception pattern may also be referred to the description of the first discontinuous transmission and reception pattern. Configuration parameters of the second discontinuous transmission and reception pattern are different from those of the first discontinuous transmission and reception pattern, for example, time-domain periods of the two are different, so as to apply to different service features.

a next slot of the first time-domain position; a slot after a plurality of slots following the first time-domain position; a moment after the first time-domain position, at which a timer corresponding to the first discontinuous transmission and reception pattern expires; or a moment after the first time-domain position, at which a first period of the first discontinuous transmission and reception pattern ends, where the first period is the time-domain period of the first discontinuous transmission and reception pattern in which the first time-domain position is located. In some possible implementations, the second time-domain position is one of:

101 102 In an example, when the network devicetransmits the second indication information via DCI, if the first time-domain position at which the user equipmentreceives the second indication information is slot1, the second discontinuous transmission and reception pattern may be activated at a next slot after slot1, such as slot2 (i.e., the second time-domain position).

101 102 102 In an example, when the network devicetransmits the second indication information via an MAC CE, if the first time-domain position at which the user equipmentreceives the second indication information is slot1, the second discontinuous transmission and reception pattern may be activated after K slots following slot1, such as (slot1+K) (i.e., the second time-domain position). The K slots may be a demodulation duration for the user equipmentto demodulate the MAC CE.

In an example, the timer corresponding to the first discontinuous transmission and reception pattern is, for example, a running timer of the second duration (on duration). For example, the second discontinuous transmission and reception pattern is activated at a moment when a DRX-on duration timer expires in a DRX pattern, or at a moment when a DTX-on duration timer expires in a DTX pattern.

101 In an example, the first period is a current time-domain period during which the second indication information is received in the first discontinuous transmission and reception pattern. The network deviceapplies the second discontinuous transmission and reception pattern at a moment when the current time-domain period ends.

102 102 101 In the embodiment of the present disclosure, the user equipmentreceives the second indication information during an activation period of the first discontinuous transmission and reception pattern, and may determine an effective position of the second indication information according to the time-domain position when the second indication information is received. Thus, the user equipmentmay determine the time-domain position when the network deviceactivates the second discontinuous transmission and reception pattern, so as to perform a corresponding energy-saving operation.
